WebOct 1, 2024 · 1. Introduction Indication of floods and events of bank erosion in ungauged catchments is often limited by the lack of hydrological data. Hydrological monitoring is usually missing in small mountain catchments. Therefore, such areas are often omitted in studies on floods and erosion. WebOct 29, 2014 · The knowledge of water storage variations in ungauged lakes is of fundamental importance to understanding the water balance on the Tibetan Plateau. In this paper, a simple framework was presented to monitor the fluctuation of inland water bodies by the combination of satellite altimetry measurements and optical satellite imagery …

WebBy definition, an ungauged basin (or catchment) is one with inadequate records, in terms of both data quantity and quality, of hydrological observations to enable computation of hydrological variables of interest, at the appropriate spatial and temporal scales, and to the accuracy acceptable for practical applications.
WebFor this, each catchment is in turn considered as pseudo-ungauged while the regionalization approach is applied to estimate its flows (Parajka et al., 2005). Then, the remainder gauged catchments are candidates of donors and regionalization procedure was applied to transfer model parameters from the catchments with the least dissimilarity index. WebThis situation is similar to that previously noted by Ballesteros-Cánovas et al. [41] in the Kullu district (Western Indian Himalayas), which could be related to the highly localized nature of extreme rainfall events in the headwater …
